Abstract: FABRICATED CONE CRUSHER               Abstract of the Disclosure A cone crusher characterized by a frame having a completely fabricated construction, an anti-spin mechanism and an improved crusher setting indicator is disclosed. The frame of the struct-ure, which is composed solely of pre-formed and/or forged members, includes a number of tubular members, a number of annular members and a number of ribs, all of which are welded together to provide a rigid, strong frame. The anti-spin mechanism is characterized by the use of a unidirectional valve and a spring loaded ball valve, thereby permitting the rotation of the mantle of the crusher in one direction while barring rotation of the mantle in the opposite direction unless a force exceeding a pre-selected magnitude is applied to the mantle. The crusher setting indicator, which is used to determine the distance between the moveable mantle and the stationary concave of the crusher includes a rod supported by the crusher, the rod abutting the cone support bearing seat of the crusher, the position of which seat is directly related to the position of the mantle. A pinion gear is coupled to the rod and the orientation of the gear is used to provide an indication of the distance between the mantle and concave.      This abstract is not to be taken either as a complete exposi-tion or as a limitation of the present invention, the full nature and extent of the invention being discernable only by reference to and from the entire disclosure.

Abstract: ABSTRACT   RECOVERY OF HEAVY HYDROCARBONS FROM OIL SLUDGE     Oil sludge      formed within a storage container is removed by penetrating tubular lances      into the sludge body      and then pumping dispersant chemicals borne by a water jet through the lances into the sludge body      with continuous drawing off and recirculation of emulsified fractions under pressure.        The sludge body      breaks down both physically and chemically to form a pumpable fluid which is drained and mixed with a larger volume of liquid oil to allow dispersion of the hydrocarbonaceous content of the emulsified fluid as a suspension in the oil volume allowing the water to settle out of the mixture, the settled water layer being thereafter drawn off.   This oil mixture is then processed in the process plant.        The dispersant chemicals emulsify or form coloidal suspension or solution of the hydrocarbonaceous content of the sludge body  in water.

Abstract: ABSTRACT OF THE DISCLOSURE   A pharmaceutical, oral-controlled release, multiple-units formulation and method for its production are provided herein.  The individual units comprise particles containing a sparingly-soluble, active substance and a dispersion-enhancing substance which is readily soluble in intestinal fluids. The dispersion-enhancing substance is present in intimate admixture with the active substance.  The particles are combined with at least one dis-integration-enhancing substance into cross-sectionally substantially-homo-geneous cores, the cores being coated with a coating which is substantially resistant to gastric conditions and which is erodable under the conditions prevailing in the small intestine.  The formulation may be prepared by a method comprising the steps co-comminuting sparingly-soluble, active sub-stance with a dispersion-enhacing substance which is readily soluble in intestinal fluids, thereby to obtain particles in which the active substance is intimately admixed with said dispersion-enhancing substance.  The particles are combined into cross-sectionally, substantially-homogeneous cores together, with at least one component which enhances the disintegration of the cores in intestinal fluids.  The cores are then coated with a coating which is substantially resistant to gastric conditions, and which is erodable under the conditions prevailing in the small intestine.  As the coating is erodable in an alkaline environment only, the active substance is not released until the units arrive at a section of the small intestine with an alkaline pH. Thus, a reduction and delay of the peak plasma concentration is obtained without affecting the extent of drug availability.  A coating of the above-defined type may also be used when the active substance is a substance which exerts an irritating effect on the gastric mucosa and/or is unstable in an acidic environment.

Abstract: ABSTRACT OF THE DISCLOSURE      An earth boring bit is shown of the type used to cut a shaft in the earth.  The earth boring bit has a central bit body which is adapted to be driven to cut a shaft and which has an outer conical surface thereon.  An outer ring segment carried on the central bit body has a conical surface for matingly engaging the central bit body conical surface whereby torque transmitted to the outer ring is transmitted through the mating conical surfaces to drive the central bit body to cut a shaft.  The mating conical surfaces are preloaded to assure drivable contact between the surfaces.  The effective cutting diameter of the earth boring bit can be varied by interchanging the outer ring segment.

Abstract: DIFFERENTIAL VENT AND BAR ACTUATED    CIRCULATING VALVE AND METHOD                  ABSTRACT OF THE DISCLOSURE     A tool for use downhole in a borehole for carrying out a backsurging  method  whereby  existing  open  perforations  are cleaned.  The tool comprises an annular body having spaced cylin-drical  walls,  each  of  which  reciprocatingly  receives  spaced pistons which move individually relative to one another.  A port is formed through each of the walls of each of the cylinders with the first port being normally closed by a first piston and the second port being normally open.  The second piston is moved to close the second port.  The tool is placed on the end of a tubing string or within a tool string and run downhole into the bore-hole.  A packer device enables the pressure between the lower annulus, the upper annulus, and the tubing to be adjusted rela-tive to one another.   A bar is then dropped down the tubing string, contacts the second piston and moves the second piston to cover the second port.  The tubing pressure is reduced to provide a  pressure  differential  between  the  lower  annulus  and  the interior of the tubing.  The first valve automatically opens when a predetermined pressure differential is achieved between the tubing  and  lower  annulus,  thereby  providing  a  predetermined pressure differential across the old perforations, and cleaning debris therefrom upon the opening of the first port.
